More than 55 police officers and three aircraft are searching for a man whose father was shot to death and mother severely beaten in Maine.

Police are looking for 45-year-old Perley Goodrich Jr., who was last seen at about 11:30 p.m. Monday leaving the home he shared with his parents in Newport, a town of about 3,000 people nearly 30 miles west of Bangor.

Steve McCausland of the Maine Public Safety Department says Goodrich is considered armed and dangerous because weapons are missing from the house.

McCausland says 76-year-old Perley Goodrich Sr. was shot to death and 64-year-old Sandra Goodrich was severely beaten. She's being treated at a hospital.

McCausland says the younger Goodrich is believed to have fled in his parents' van, which was abandoned on a dirt road two miles from the home.
